Speaker: Dr. Gerard T. Schuster Talk Title Futuristic Seismology Today: Boomless Seismology
Abstract Boomless seismology is the recording of ambient seismic noise and transforming it into useful signals. The signals include body waves and surface wave reflections that can be used to image the smooth velocity structure of the earth. This is a scientific revolution for 21st century seismology. We now show that boomless seismology, also known as ambient noise seismology, can also be used to image the sharply varying structures in the earth. I show recent results from Abdullah AlTheyab (KAUST) and Prof. Fan-Ch Lin (U of Utah) that reveal hidden fault structures below Los Angeles and North America. The method they developed is called natural migration that migrates scattered surface waves back to their place of origin, the fault scarps. Results from migrating US Array data and traces recorded by a dense receiver array near Los Angeles clearly reveal the presence of hidden geological anomalies.
Speaker: Dr. Renato Rocha Lopes Talk Title Traveltimes for data acquisitions with topography
Abstract Several land acquisitions are performed on non-flat topographies, with source and receivers at different elevations. In this talk, we briefly review some effects of the topography on seismic processing algorithms, as well as some classical solutions, such as static corrections. Then, we discuss the motivations and preliminary results for an ongoing research on a traveltime equation that provides an interesting solution to the topography problem by directly including the elevation information in the traveltime. The proposed equation shares the benefits of methods such as the common reflection surface (CRS), allowing for the appropriate combination of several neighboring CMPs for stacking and parameter estimation.

Speaker: Ibrahim Al-Hokail Talk Title Simulation of single-sensor seismic acquisition with conventional seismic recording systems
Abstract Modern 3D seismic data surveys aim to acquire cost-effective broadband seismic data that are sampled uniformly in all azimuths and offset ranges. This uniform full azimuth sampling facilitates processing and interpreting seismic data in the prestack domain rather than in the conventional poststack domain. These requirements have prompted the development and deployment of what is known as single-sensor seismic data acquisition recording systems, which are known to have receiver recording channels in excess of 100,000 channels. Though 100,000 receiver channels may sound superior to conventional seismic recording systems, practices of highproductivity techniques, such as the distance-separatedsimultaneous shooting technique to achieve fast acquisition, have limited their full potential. As a result, fundamental processes to improve signal-to-noise ratio, such as digital receiver group-forming, have become impractical. Severe and time-consuming noise attenuation algorithms have to be applied on the single-sensor seismic data to bring up their fidelity for further image and inversion processing. Consequently, problems in increased data volume, turn-around time, cost and data quality have been observed. Alternatively, high-channel-high-productivity conventional seismic recording systems can be used to satisfy most modern seismic acquisition requirements for comparable data quality, faster turn-around time and lower cost. In this presentation, we will offer our perspectives on these issues and show examples of both types of datasets.

Speaker: Tim Perrin Talk Title Seismic Acquisition. So Just What Data Is on Your Field Tape?
Abstract Modern seismic crews have evolved to become highly efficient 24 hour operations, often employing over 500 people and working in remote and difficult terrains. In recent years there has been an exponential rise in the number of traces recorded per shot, number of shots per day and the petabytes of data per year; but not all seismic traces are created equal. In this presentation, we look briefly at some of the fundamental choices when recording seismic data and the implications for high production recording in particular. After that we show the importance of managing time and spatial distribution of shots to avoid cross record interference. It will also be shown that single sensor data recorded with digital accelerometers has a natural 6dB/octave bias towards high frequencies. So, recording geophones and accelerometers side-by-side would result in accelerometer data having a noisier appearance than the velocity data from geophones. However, if we were to integrate the acceleration data to velocity it would be equivalent to the geophone data with the benefit of recording several octaves additional bandwidth
Speaker: Andre Hajjar Talk Title Need of Real Time Acquisition for seismic measurements
Abstract It has become very important to develop an automated seismic measurements and analysis system. A system that involves: 1- Obtaining reliable measurements in extreme environments from different kind of sensors and different manufacturers

2- The use of many data acquisition channels connected to many system nodes, the capabilities of reliability, availability, serviceability, and manageability are becoming more important. 3- Gathering this large amount of data, processing it and interpreting it in an automated way. This session will addresses each of the the above steps and showcase how it has ancient structure and in the oil field. case studies, such as "Burj Khalifa" in
